Abstract
The influence of the helium-neon laser emission on HSA was investigated at present work by means of the fluorescent probe MNBIS (4-morpholino-7-oxy-7-H-benzo-[de]-benzo-[4,5]-imidazo-[2,1-a]- izoquinolin-5-sulfonic acid) sensitive to protein conformational changes using. Fluorescence spectra parameters of the probe and kinetics of probe interaction with protein molecules were analyzed. Possible mechanisms of the helium-neon laser irradiation on water-protein solution structure are discussed.
